I had an issue with water filling the hatch. Replaced all hatch seals and siliconed around their securing studs. No improvement. Climbed into the hatch and had a friend spray it down with a water hose. The culprit was the tail lights. Replaced tail light seals and no improvement. It was the...

Thank you for this. In the process of modifying and relooming my harness now. Your pics are going to be a BIG help.

^ This. Had a similar issue that turned out to be a cracked #4 intake valve guide.

I' m disappointed to see that some of my longest, most informative threads could not be recovered. Still glad to see the site is back up with whatever content could be salvaged.

Check your turbo and intake pipe for oil. None there? It’s your valvestem seals. Mine went bad from sitting over 10 years and engine had less than 3k mi on it. Originally I thought it was the turbo, and there was oil in the pipes. Had it rebuilt, no more oil on impeller wheel or in intake pipes...

I diagnosed and resolved the spark blowout issue a couple days after picking the vehicle up from the tuner. He was saying the power dip was likely due to the restrictive factory exhaust manifold, however, I have never seen that power drop on any of my past dyno runs. As soon as I drove the...

My 7M just put down 516whp. This should bring me from #21 to #15. :icon_bigg Can I be updated on the list? -100hp dip at 6200rpm was due to spark blowout and has since been resolved by tightening plug gap to 24. https://www.youtube.com/watch?v=ZmsoiVwJuBI

What I did was finally get the Supra back. After 5 months at the tuners, the Supra is home. Pulls like a freight train and will break traction in 2nd and 3rd under boost with 275 Gforces on the rear. Dyno video was terrible quality with crackly audio, so a dyno chart will have to do for now...

^ As far as I know, a complete Turbonetics Bolt-On will have their "T" logo on the center section and turbine housing. Compressor covers have "Turbonetics" cast into the front. Anything else is likely a Frankenstein of some sort from multiple manufacturers. These turbos are old, things break...

Pretty sure mine's running the .68 turbine housing. Can't find the Turbonetics catalog anymore. I came across it a few years ago online.

I’m not sure why they never list AR’s. Other than an old Turbontics catalog I came across, I’ve yet to see any specifics. I do know the two most common I have come across are .63 and .81.

All that had been discussed is that your turbine housing is Turbonetics. Your center section is not based on the type of oil feed lines yours uses and the compressor cover is clearly not Turbonetics either.

Wow over 30 bids and up past $20k. Can’t imagine how high it’d go with a gray interior.

Once again, if the housing has a Turbonetics logo, it’s Turbonetics. Turbonetics did not produce the housings until after HKS discontinued their 7M Sport Turbos. So there’s no way HKS could have used Turbonetics as a supplier. Reg didn’t remember seeing the “T” logo on his turbine housing...

You've posted a scan of an itemized 18 year old email from Reg Riemer to the previous buyer. Not from Turbonetics and I see no shipping invoice from HKS. Not sure what you're trying to prove or disprove. It's already been discussed that the hotside is a later cast from Turbonetics, not HKS. As...
